The problem here is that it does not state the date of purchase of the device, only the start date of the contract. I know that these are the same date but insurance, being insurance, need something that specifically states the date of purchase.

I only have a certain amount of time in which to process this claim under the terms & conditions of my policy. The delays I'm experiencing with trying to get the correct information are putting that deadline at risk. If I can't get this sorted out tomorrow I will not be able to make the claim for my phone!
